Just got back from the "after" dyno session. After installing PPC long tube headers with 3" y-pipe & no cats.

Here's the stats:

Before:
60,000 miles
Air lid & K&N, G-MAF, HPP-3, cut EGR tube, 6-sp, 3.23 gears
12/20/02, 40 degrees, rain
323 RWHP @ 53000rpm , 334 RWTQ @ 4600rpm

After:
70,000 miles
Same mods except header system
09/03/03, 75 degrees, overcast
348 RWHP @ 5700rpm , 356 RWTQ @ 4600rpm

Coooollllllll.................
Now I can install the cam......

Excellent gains! I like the way you are dynoing after each mod to see how much every change increases your power.

Do you like the way it sounds now? Is the rest of your exhaust system stock?

Thanks for the kind words..! [Wink]


Sound - With the stock WS6 exhaust (same as the stock SS exhaust...no special SLP stuff), and no cats, the exhaust sounds very much like stock but with an attitude [Cool] .

A Random Technology 3" Cat-Back is going on next...By the look of the "muffler" I think it will be ...umm... louder.

Hey... you Michigan guys... I'm a native Michigander too...grew up doing 1st gens w/big blocks (BIG ... big blocks) on Woodward in the '70s. I missed ya while I was there for DreamCruise!

Gordon,

Is that with tuning or without?

Is it mandatory to "tune" when you install headers?

Rock

That is only with the canned HPP-3 program, both before the headers & after.

No, tuning is NOT required. However, if you were to tune.... the numbers would be greater.

I did notice , while on the dyno, that it was running a bit rich at the top end (a little bit black exhaust). This is what I expected. From what I understand, the LS1 likes to be on the shy side of 12:1 AFR to make the best power.

Nice results.

I've admired the headers and the rest of the kit on several occassions now [Cool]

LQQKing forward to getting them installed this winter. [Smile]

I'm considering ordering mine with the hi-flo cats after the BG Gathering.

Are there ANY issues with install, clearance, proximity to parts, banging, etc.
 
Posted by M3EATER (Member # 1731) on :
 
The only issue would be that on a lowered car ... the cat on the driver's side is a bit low.

My car is 1.5" to 2" lower than stock & I am running without the cats. The lowest part of the driver side pipe is about 3" from the ground. A cat would be 1/2" lower than that. Now remember, that is with my car lowered. A non-lowered car would be 1.5" to 2" more clearance.

Also, I have one customer with a convertible. He had problems with the driver side header. Apparently, the front subframe on the convertible is a bit beefier.

Gordon,

Another question for you.

How "easy" is the install? Is it a true bolt on that I could do in my garage with regular hand tools? How long would it take?

My car is in the sig below.

Rock
 
Posted by M3EATER (Member # 1731) on :
 
Install is as "bolt-on" as you're ever going to get! It's still a 10 hour job when you're laying on your back.

I highly recommend air tools .... a 3/8" drive air ratchet is almost a MUST.

You can do most of the install on a set of high ramps or on jack stands. However, the driver side requires the car to be a bit higher while sliding the header in.

Other than that..... sure, it's easy............. [Big Grin] [Wink] [Big Grin] [Wink]

Gordon.

Those are some nice numbers. Quite a jump in power and torque.

How is the car after you "miishap" in the winter. I take it everything worked out.

Also, are you planning to be at the BG F-Body Celebration?

The car is fine now.... more or less. Still a couple issues to go back for.

I've been fretting over the Bowling Green thing... I don't think it will work out this year. Just too much going on.

Can anyone who has the PPC headers provide both their minimum ground clearance AND what the ground clearance of the what the body is at, at the closest location. It will give me a real good idea of what my ground clearance would be. How does the clearance compare to other headers??? I just don't want to loose the exhaust going over a speed bump. [Wink]

Kevin,

I'll measure all of the areas on the PPC car for you (and everyone else), over the weekend.
